Eight groups, five session strategies

Three runs per strategy. Costs are means in USD; time is the median in minutes. Pass counts measure complete delivery. Input, cache reads, cache writes and output are all included. ≥ marks incomplete usage records, a lower bound rather than cheaper successful delivery.

Cost and time include native compaction, but exclude prior development and shared-summary preparation. Prices are frozen runtime estimates, not invoices. For functional / observational acceptance, use the article’s interactive explorer.
